Title: | Deriving Economic Values for Reaction Norms of Growth in Pigs | Contributor(s): | Hermesch, Susanne (author) ; Amer, Peter (author) | Publication Date: | 2013 | Handle Link: | https://hdl.handle.net/1959.11/14331 | Abstract: | Slopes of reaction norm models, also called reaction norms (RN), are alternative traits used in animal breeding for selection of genotypes that perform more consistently across a range of environments. Environmental sensitivity is of economic importance when the environment where selection takes place differs considerably from the commercial environment of slaughter pigs. The position on the environmental trajectory where intercept of reaction norm models is defined influences the economic values (EV) for slope and intercept. This position has to correspond to the trait definitions of intercept and slope of reaction norm models used to estimate variance components. The magnitude of EV for RN depends on the difference between the selection and production environments and the EV for the trait of interest. Economic values for RN may be negative or positive depending on whether the production environment is below or above the selection environment. Non-linear EV for growth across the environmental trajectory had minimal impact on the EV for RN of growth. Further genetic and economic analyses of extensive industry data are required to better quantify the economic importance of RN in pig breeding. | Publication Type: | Conference Publication | Conference Details: | AAABG 2013: 20th Conference of the Association for the Advancement of Animal Breeding and Genetics: Translating Science into Action, Napier, New Zealand, 20th - 23rd October, 2013 | Source of Publication: | Proceedings of the Association for the Advancement of Animal Breeding and Genetics, v.20, p. 475-478 | Publisher: | Association for the Advancement of Animal Breeding and Genetics (AAABG) | Place of Publication: | Armidale, Australia | ISSN: | 1328-3227 | Fields of Research (FoR) 2008: | 070201 Animal Breeding | Fields of Research (FoR) 2020: | 300305 Animal reproduction and breeding | Socio-Economic Objective (SEO) 2008: | 830308 Pigs | Socio-Economic Objective (SEO) 2020: | 100410 Pigs | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | http://www.aaabg.org/aaabghome/proceedings20.php |
